SEQUENCE

A hymn of joy in varying meter sung or recited before the Gospel at Mass on certain feast days. Thos that have survived are the Easter Victimae Paschali, the Veni Sancte Spiritus at Pentecost, and the Lauda Sion for Corpus Christi. The Dies Irae at some Masses for the Dead is not, strictly speaking, a liturgical sequence. (Etym. Latin sequentia, a following, sequence.)
